Created Unassigned: Set resolver sequence [8812]

agladshteyn — Mon, 17 Jun 2013 15:21:03 GMT

I have a complex object and using a custom resolver to resolve the values for its properties. I was wondering if there is a way to specify a sequence or order in which the properties will be resolved. For example, if I have 3 properties in an object: Property1, Property2 and Property3, which appear in the object in that order. However, Property1 depends on Property3, so I need to resolve Property3 before I resolve Property1. Is there any way to control that?

Thanks,
Alex

Created Unassigned: Performance Issue [8791]

shifali — Mon, 10 Jun 2013 06:18:37 GMT

Hello,

I am working on a project using .Net technologies. In our peoject, we are using Entity Framework/Linq/Automapper/POCO.

We use below functions of Automapper as -
1. Automapper.CreateMap() - to declare maps.
2. Automapper.Mapper.Map() - to map source to destination type (i.e. Data Access object to POCO entities).

But, somehow Automapper is giving performance hit to some extent. So, I was trying to figure out am I making correct use of the plug in?

It would be great if I could get valuable help from anyone who has worked/studied about this plug-in.

Thanks in advance!

One problem I'm seeing is that say your customer domain object had the property CustomerName instead of just Name then the DTO needs to have the property CustomerCustomerName It would be good if Automapper could check the property isn't prefixed already with the class name.

Why is the advantage of using ResolveUsing instead of just UseValue within a ForMember call?

Closed Issue: Mapper.Map error [8372]

jbogard — Wed, 24 Oct 2012 18:22:30 GMT

I have an Entity Framework database that I am trying to update a record in. I have created all the AutoMapper.Mapper.CreateMap entires. I have also used AutoMapper.Mapper.AssertConfigurationIsValid() to validate off of the CreateMap's and add all the corresponding ForMember's to them and not the AutoMapper.Mapper.AssertConfigurationIsValid() doesn't generate any errors at all. However when I call AutoMapper.Mapper.Map on the 2 main objects it still says there is an unsupported mapping configuration and it won't tell me what it is, but the fact AutoMapper.Mapper.AssertConfigurationIsValid() says everything is correct seems to contradict what's going on.

Closed Issue: AutoMapper caching objects when mapping twice [8321]

jbogard — Fri, 28 Sep 2012 15:45:41 GMT

When you have a tree heirarcy of objects, and the same value exists in two places of the tree (but with different child values), and when mapping the second instance of the item - it uses the child values of the first instance, instead of re-evaluating what the child values should be.

Here is my example:
class Tag {
int Id {get; set;}
string Name {get; set;}
IEnumerable<Tag> ChildTags {get; set;}
}

public void Test()
{
var source = new List<Tag>
{
new Tag { Id = 1, Name = "Tag 1", ChildTags = new List<Tag>
{
new Tag { Id = 2, Name = "Tag 2", ChildTags = new List<Tag>
{
new Tag {Id = 3, Name = "Tag 3"},
new Tag {Id = 4, Name = "Tag 4"}
}
}
}
},
new Tag { Id = 1, Name = "Tag 1" },
new Tag {
Id = 3, Name = "Tag 3", ChildTags = new List<Tag>
{
new Tag {Id = 4, Name = "Tag 4"}
}
}
};

Mapper.CreateMap<Tag, Tag>()
.ForMember(dest => dest.ChildTags,
opt => opt.MapFrom(src => src.ChildTags));
var result = Mapper.Map<IList<Tag>, IList<Tag>>(tags);
}

In the result
- the first instance of Tag 1 (ie source[0]) and all of its children are perfect
- the second instance of Tag 1 (ie source[1]) has all the children of the first instance - it should not have any children
- the second instance of Tag 3 (ie source[2]) does not have any children - it should have Tag 4 as a child

I have following class

{
Value = amount;
CurrencyCode = CurrencyCode.USD;
}

public decimal Value { get; set; }
public CurrencyCode CurrencyCode { get; set; }

// define implicit Money-to-Nullable<double> conversion operator:
public static implicit operator double?(Money money)
{
return Decimal.Zero == money.Value
? null
: new double?( Convert.ToDouble(money.Value));
}
}

When I try to map it to I getting Specifica cast is not valid exception.

Can i map two types to form a destination type? Basically I am looking at merging two types to form destination type. Please help.

The Automapper GitHub wiki doesn't appear to support search nor appear to be indexed. Even googling with a "site:github.com" constraint doesn't turn up anything more than bug reports. Makes it difficult to find documentation relating to certain functions/APIs in AutoMapper.

AutoMapper has moved to GitHub

AutoMapper has completely moved to GitHub:

https://github.com/AutoMapper/AutoMapper

The site can be found at http://automapper.org

All issues should be reported on GitHub. No issues will be responded to on CodePlex.

I can't turn anything off on CodePlex without deleting the whole site, which would be very confusing.

The latest downloads can be found at NuGet or at GitHub.

Commented Issue: Multiple mappings for the same type [4036]

arfanbaig — Tue, 11 Oct 2011 13:54:57 GMT

Hi,

I'd like to suggest to optionally specify a name for a mapping allowing to have multiple mappings of the same type with different configurations.

e.g. Mapper.CreateMap<Order, OrderDto>("OrderMapping");

I see a lot of value in that especially in combination with the Ignore configuration.

In one of my projects I currently implemented my own mapper which maps nested objects based on input parameters. Some of my service requests allow the consumer to specify whether nested collections are loaded. For example in one instance a consumer wants to load a collection of orders without having the details such as the products attached. In an other instance the consumer may want to retrieve orders with associated products. The mapping for both cases would be of the same type but the Ignore configuration would be different.

This is similar to unity where you can configure a type and a name to distinguish between various type configurations of the same type. :)

@jbogard, is this Multiple mapping functionality available* now in the Automapper? (just a correction)
